It's weird to sell a new game only in a bundle. Makes me think it won't be good enough to sell on its own.
But I'll consider buying this just for the original Ecco. It remains one of the most atmospheric games I've ever played. That music, and the feeling of claustrophobia, just incredible.
When I was a kid, Big Blue freaked me out, so I rarely made it past him. I know you don't fight him or anything; I just used to get scared and stop playing. I've always wanted to revisit the game as an adult.
